Demo 'Der Hof'
The demo-scene 'Der Hof' demonstrates the calculation of real-time shadows. Real-time effects like shadows and bump-mapping are rendered by using vertex-shader and pixel-shader programming,
thus adding to the graphical quality of the scene without overly impacting it's performance.
The shadow volumes are initiallly genereted with degenerate quads and are then deformed by the vertex shader of the light source.
The method used for shadow calculation is called "depth-fail-method" which eliminates 'inversion problems' if the camera position
happens to be inside a shadow volume. This demo was optimized for shader 2.0 to make visual effects like water and bump-specular mapping possible.
